CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit of European Community Plant Variety Rights application filed on Mar. 13, 2018, File No. 2018/0756, the entire contents of which are incorporated herein by reference for all purposes.

‘KLEDH17008’ has not been made publicly available for more than one year prior to the effective filing date of the present application.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Dahlia, botanically known as Dahlia sp., and hereinafter referred to by the variety name ‘KLEDH17008’. ‘KLEDH17008’ originated from a cross-pollination conducted between September to November 2013 in Stuttgart, Germany between the proprietary female Dahlia variety ‘KLEDH13033’ (U.S. Plant Pat. No. 26,741) and the commercial male Dahlia variety ‘Dahlette Surprise Louise’ (patent status unknown).

The seeds from the cross-pollination were sown and plants were grown in a greenhouse for evaluation, where an individual plant designated ‘KLEDH17008’ was selected from the group in May 2014 of plants in Stuttgart, Germany. In February 2015, ‘KLEDH17008’ was first vegetatively propagated by terminal cuttings. ‘KLEDH17008’ was found to reproduce true to type in successive generations of asexual propagation via terminal cuttings.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Stuttgart, Germany.

-   -   1. Yellow flowers; and     -   2. An upright plant habit.

DESCRIPTION OF THE PHOTOGRAPH

The following detailed descriptions set forth the distinctive characteristics of ‘KLEDH17008’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. The photo is of a 13-week-old plant grown indoors in Stuttgart, Germany under greenhouse conditions in April 2014. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^(th) edition (2007).

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘KLEDH17008’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany in May 2018. Data was collected on plants potted in week 11 and grown in a controlled greenhouse environment approximating those generally used in commercial production, pinched once, with a growth regulator, and under natural light. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^(th) edition (2007).
